Deep learning-based histopathological assessment of tubulo-interstitial injury in chronic kidney diseases.

Background: Chronic kidney disease (CKD) causes progressive and irreversible damage to the kidneys. Renal biopsies are essential for diagnosing the etiology and prognosis of CKD, while accurate quantification of tubulo-interstitial injuries from whole slide images (WSIs) of renal biopsy specimens is challenging with visual inspection alone.

Methods: We develop a deep learning-based method named DLRS to quantify interstitial fibrosis and inflammatory cell infiltration as tubulo-interstitial injury scores, from WSIs of renal biopsy specimens.

Intestinal butyric acid-mediated disruption of gut hormone secretion and lipid metabolism in vasopressin receptor-deficient mice.

Objectives: Arginine vasopressin (AVP), known as an antidiuretic hormone, is also crucial in metabolic homeostasis. Although AVP receptor-deficient mice exhibit various abnormalities in glucose and lipid metabolism, the mechanism underlying these symptoms remains unclear. This study aimed to explore the involvement of the gut hormones including glucagon-like peptide-1 (GLP-1) and microbiota as essential mediators.

SUrvey of renal Biopsy registry database and Anticancer dRUg therapy in Japan (SUBARU-J study).

Background: Kidney complications associated with anticancer drug therapy have greatly increased recently. We aimed to investigate the real-world clinical outcomes of anticancer drug therapy-associated renal complications in Japan using the national kidney biopsy database, Japan Renal Biopsy Registry (J-RBR).

Methods: From 2018 to 2021, 449 cases from 49 facilities identified as 'drug-induced' histopathology in the J-RBR were screened, of which a total of 135 were confirmed as anticancer drug-related cases and included in the analysis.

Is Intraoperative Blood Loss Volume in Elderly Cervical Spine Injury Surgery Greater in Patients with Ankylosis? A Multicenter Survey.

Introduction: Preoperative estimations of blood loss are important when planning surgery for cervical spine injuries in older adults. The association between ankylosis and blood loss in perioperative management is of particular interest. This multicenter database review aimed to evaluate the impact of ankylosis on surgical blood loss volume in elderly patients with cervical spine injury.

Reduction of urinary felinine in domestic cats with renal diseases leads to decreased catty odor.

Cats with progressive renal diseases often exhibit a weakened urinary odor, in contrast to normal cat urine which emits odorants with catty odor, such as 3-mercapto-3-methyl-1-butanol, 3-mercapto-3-methylbutyl formate, 3-methyl-3-methylthio-1-butanol, and 3-methyl-3-(2-methyldisulfanyl)-1-butanol. Felinine, an amino acid, is a precursor of these odorants and metabolized from its precursor, 3-methylbutanol glutathione (MBG), via 3-methylbutanol-cysteinylglycine (MBCG). While previous studies have reported felinine excretion in normal cats, its levels in cats with renal diseases remain unclear.

Adult severe community-acquired pneumonia with bloodstream infection caused by ψUSA 300: A case report.

We report the first case of fatal community-acquired pneumonia with concomitant bloodstream infection caused by the ψUSA300 strain of methicillin-resistant Staphylococcus aureus (MRSA). The isolate was positive for Panton-Valentine leukocidin (PVL) gene, with a unique 12-base pair deletion in the ccrB2 gene, differentiating it from the canonical USA300 strain. Despite aggressive therapeutic interventions, the patient developed multiple complications, including septic shock, which ultimately proved fatal.

Effects of Prospective Audit and Feedback in Patients with Extended-Spectrum -Lactamase-Producing Bacteremia.

Antimicrobial stewardship (AS) Guidelines by the Infectious Diseases Society of America recommend employing prospective audit and feedback (PAF) as an effective intervention in AS programs. Since July 2022, our hospital has implemented PAF for all patients with positive blood cultures, including those with extended-spectrum -lactamase (ESBL)-producing (EC) bacteremia. Our study examined the effect of PAF on clinical outcomes in patients with ESBL-EC bacteremia.
